1 Using the completed Anchor Chart/Grid and Venn Diagram from the previous lesson, the teacher leads a class demonstration on the dependence of species on one another in an ecosystem. Using pictures of species on the board the teacher will demonstrate how to map the interconnectiveness of these animals on one another. This lesson will help students gain a thorough understanding of the dangers that affect different organisms and solutions that can help preserve their organism s ecosystem. This will showcase how the efforts of Bring Back the Wild impact each species ecosystem positively. Time Frame 2 x 40 minute lessons Pre-Assessments The students will have demonstrated the ability to; 1. Develop an Anchor Chart that lists the basic needs of Living Things. 2. Demonstrate the understanding of similarities and differences of a number of species. Specific Objectives 1. The students will develop an understanding of the dependence of species on one another in an ecosystem. 2. The students will recognize the different interactions of animals in an ecosystem. 3. The students will develop an understanding of how to generate a simple ecosystem map. Ministry Expectations Science Curriculum 1.1 identify personal action that they themselves can take to help maintain a healthy environment for living things, including humans 1.2 describe changes or problems that could result from the loss of some kinds of living things that are part of everyday life 3.4 describe the characteristics of a healthy environment, including clean air and water and nutritious food, and explain why it is important for all living things to have a healthy environment Language Curriculum Oral Communication 1.5 use stated and implied information and ideas in oral texts, initially with support and direction, to make simple inferences and reasonable predictions Reading 1.4 demonstrate understanding of a text by retelling the story or restating information from the text, including the main idea 1.6 extend understanding of texts by connecting the ideas in them to their own knowledge and experience, to other familiar texts, and to the world around them Pg. 1

2 Writing 1.2 generate ideas about a potential topic, using a variety of strategies and resources 1.4 sort ideas and information for their writing in a variety of ways, with support and direction Specific Objectives 1. The students will develop an understanding of the dependence of species on one another in an ecosystem. 2. The students will recognize the different interactions of animals in an ecosystem. 3. The students will develop an understanding of how to generate a simple ecosystem map. Materials Anchor Charts, Grid and/or Venn Diagram from previous lesson hanging in view for access by students. Bulletin Board Print pictures of a variety of animals in a given ecosystem. Provided or use from magazine sources. Coloured yarn Procedure Anticipatory Set/ Motivation The teacher will begin by discussing the following: Now that we know a bit more about the Grizzly Bear, Jefferson Salamander, Wolverine or Peregrine Falcon, we are going to expand our learning and understand how each of these species connect to other living organisms. For example, we know that Grizzly Bears like to eat salmon but what does salmon like to eat and why is it important to know that? Students will access Anchor Charts and Grid to identify the Basic Needs of animals as they progress through the lesson. The teacher will introduce a number of animal photographs and apply them in various places on the Bulletin Board. The teacher will ask the students to show the animals are related. Pg. 2

3 Instructional Steps The students will provide responses about how organisms interact with each another. The teacher will ask students to put three groups of three together based on how they connect. Then the teacher will assign each group of animals a colour yarn and students must connect the species in the correct order of who eats who. Conclusion Steps The teacher will identify the term Ecosystem Map as a title and explain that what the students have created. The students will then be provided with a worksheet in which they will create an ecosystem map with a smaller number of animals. Formative Evaluation Summative Evaluation Enrichment / Remediation 1. The teacher will observe students participation during class discussions. 2. The teacher will collect and assess the student responses on provided work sheet. 1. The teacher will collect and assess student worksheet for understanding of species relationships. The teacher will ensure Mastery students be provided a larger number of species to challenge their understanding of the concept. The teacher will provide struggling students with animals that are easy to understand and establish relationships for during the exercise. Follow up The follow up lesson will involve investigating the impact of an animal being taken out of the ecosystem. Students will be challenged to see what the impact would be on the rest of the ecosystems. Pg. 3
